Claudoscope is a free, open-source macOS menu bar app that gives Claude Code users a full session history browser, cost analytics, and search across all their coding sessions. It reads directly from local JSONL session files in ~/.claude/projects/ and works entirely offline — no telemetry, no data sent anywhere, fully MIT-licensed. The tool estimates costs from raw token counts against published API pricing, giving developers a clear picture of where their Claude Code spend is going across projects and sessions. It also automatically scans for leaked API keys and credentials in session content — effectively adding a passive security audit to every session review. Claudoscope fills a real gap: Claude Code's built-in /cost command only covers the current session. Claudoscope gives historical visibility and project-level analytics. It works with any Claude Code deployment including Enterprise API setups where cookie-based session trackers fail. Built and maintained by an indie developer, free forever.

Zindex is a diagram runtime built from the ground up for AI agents. Instead of generating one-shot diagram images, agents interact with Zindex through a Diagram Scene Protocol (DSP) — a structured set of 17 operations like add_node, update_edge, or apply_layout — and the platform validates the inputs, computes a proper layout using a Sugiyama-style hierarchical engine, and maintains a versioned, persistent diagram state that renders to SVG or PNG on demand. The pitch is that current diagram generation with tools like Mermaid or Graphviz is stateless and brittle: the agent generates a full diagram string, the renderer chokes on a syntax error, and you start over. Zindex makes diagrams a first-class collaborative artifact between agent and human — you can issue an operation, see the result, reject it, and the diagram rolls back. It supports architecture diagrams, BPMN flowcharts, ER diagrams, sequence diagrams, org charts, and network topology graphs, with 40+ built-in validation rules to catch invalid states before they ever render. Zindex is a SaaS product with an API-first design, though pricing has not been publicly disclosed. The project surfaced on Hacker News in April 2026, where the community was intrigued but skeptical — particularly around why this couldn't be done with structured Mermaid outputs, and whether the protocol overhead was justified for most agent use cases.
Reviewer scorecard
“As someone who runs Claude Code 8+ hours a day, this is immediately valuable. I had no idea which projects were burning through tokens until I installed it. The leaked credential detection is a bonus I didn't expect — it already caught a test API key I'd forgotten to rotate.”
“The Diagram Scene Protocol is a genuinely clever idea — treating a diagram as a mutable data structure rather than a generated string. Anyone who's debugged malformed Mermaid output from a coding agent will immediately see the appeal. The 40+ validation rules alone would save hours of prompt-tuning.”
“This is fundamentally a log file reader with cost estimation math. Anthropic could ship this natively in Claude Code in a single PR and make Claudoscope obsolete overnight. The gap it fills is real, but the risk of deprecation-by-inclusion is very high for an indie-maintained tool.”
“Claude and GPT-4o already produce perfectly serviceable Mermaid and Graphviz diagrams for 90% of real-world needs. Adding a proprietary protocol layer, SaaS pricing, and a dependency on a startup's uptime is a lot of overhead for incremental quality gains. Wait until the pricing is public and the API is stable.”
“The emergence of cost-tracking tools for AI coding sessions is a leading indicator of developer maturity. When developers start optimizing their AI spend like they optimize their AWS bill, we've crossed a real threshold. Claudoscope is primitive, but it's the first version of what becomes a full AI development economics dashboard.”
“As agents become long-lived and stateful, the artifacts they produce need to be stateful too. Zindex is building infrastructure for a world where agents maintain living documents — diagrams that evolve over days of autonomous work, not one-shot outputs. That's an important category even if it seems niche today.”
“Indie developers and freelancers who need to track Claude Code costs against client projects will love this. The project-level breakdown finally makes AI tool costs legible as a line item on a client invoice — something that's been surprisingly hard to do until now.”
“For technical content creators — engineers documenting architecture, product designers mapping flows — having an agent that can build and revise a diagram collaboratively rather than regenerating from scratch every time is genuinely useful. The SVG/PNG export story matters for real deliverables.”
